Dear sirs,
I have encountered the following problem (UnicodeDecodeError) when I run
the 'r.watershed', one of the GRASS GIS tools, on QGIS. Could you tell
me how to solve this problem? The operating system, version of QGIS, and
error log are as follows:
OS: Windows 10 Pro, 64 bit
QGIS version: 3.22.16
Error log:
QGIS version: 3.22.16-Białowieża
QGIS code revision: 6f08e4d7
Qt version: 5.15.3
Pythonバージョン: 3.9.5
GDAL version: 3.6.2
GEOS version: 3.11.1-CAPI-1.17.1
PROJ version: Rel. 9.1.1, December 1st, 2022
PDAL version: 2.4.3 (git-version: f8d673)
